ATTORNEYS PHOTOGRAPIIIC PROCESSOR HAVING MOVEMENT RESPONSIVE ROTATION CONTROL CROSS-REFERENCE TO RELATED APPLICATIONS Reference is made to commonly assigned copending US. Pat. application Ser. No. 454,543, entitled Tubular Processor," filed May 10, l965 in the name of Roy D. Porter.

BACKGROUND OF THE INVENTION l. Field of the Invention The present invention relates to an apparatus for processing photographic materials and more particularly to such apparatus having improved structural means for selectively, imparting processing rotation to a tubular processing drum and disposing the processing drum for liquid introduction and/or discharge.

2. Description of the Prior Art Various cylindrical drum processors of the type adapted to receive photographic materials and processing liquids and be rotated around the drum axis to provide intimate contact between the materials and liquids are known in the photographic processing art.

Recently a novel photographic drum-type processor has been devised which, when in one orientation, allows introduction of processing liquid into the processing drum while a used processing liquid in the drum is drained. This novel capability is achieved by provision ofa storage reservoir within the drum and by locating the liquid introducing and discharge openings at opposite ends of the drum. One embodiment of such a tubular processor is disclosed in copending US. application Ser. No. 454,543, noted above. In such a processor, the processing liquids are introduced and drained while the processing tube is orientated with its longitudinal axis in a generally vertical position. When it is desired to cause the liquid in the reservoir to contact the processing chamber of this processor, the tube is reoriented to a generally horizontal position. In the horizontal position the processor is properly disposed for processing rotation about its longitudinal axis.

SUMMARY OF THE INVENTION It is therefore one object of the present invention to provide means for conveniently moving such a processor between a stationary vertical disposition and a rotating horizontal disposition.

It is another object of the present invention to provide an improved support and drive means for facilitating the use of a drum type processor.

It is another object of the present invention to provide an improved processing apparatus of the type utilizing a drumlike processing chamber.

It is a further object of the present invention to provide an improved support and drive control means for a tubular processor of the type which is advantageously filled in one orientation and rotated in another orientation.

Yet another object of the present invention is to provide an improved photographic processing apparatus having means to facilitate introduction and discharge of processing liquid into and from the processing chamber and automatic control of the transmission of rotative drive to the processing chamber.

Another object of the present invention is to provide improved means for controlling the transmission of rotative drive to a tubular processor.

Still another object of the present invention is to provide improved means for selectively, by a change of drum orientation, connecting rotating drive to a tubular proc essing drum and supporting the drum in a stationary position for introduction of processing liquids.

Briefly, one embodiment of the present invention accomplishes these and other objects by means comprising a tiltable cradle which loosely supports a processing drum of the type described, in a manner affording a small movement of the tube or drum with respect to the cradle during movement of the cradle from a generally vertical to a generally horizontal position. A pair of spaced rollers are mounted on the cradle in a location such that a drum supported in the cradle will rest by gravity on the rollers when the cradle is in its horizontal position. Rotative drive is provided for at least one of the rollers and is transmitted to a supported drum when the cradle is in its horizontal position. Because it is often desirable to continue processing operations without manually shutting off the processing tube drive, the present invention provides means which are responsive to movement of the cradle to its vertical, processor-filling position for disengaging rotating drive from the tube, In this embodiment of the invention, hereinafter disclosed in detail, this inactivation of tube rotation is accomplished by providing the limit for the cradles vertical movement slightly beyond the tubs arc of travel from horizontal to vertical position. In this manner the processing tube will fall away from the rotating rollers and rest in a stationary position in the cradle for filling.

It will of course be appreciated that the same objective can be achieved by providing inclined support structure at the bottom of the cradle, in its vertical position, so that a processing tube resting thereon will fall away from the rotating drive in any generally vertical cradle position. Likewise the objective can be achieved by mounting the drive rollers separate from the cradle, in a horizontal position and selectively moving the cradle between the vertical filling position and a horizontal position in which the processing drum or tube supported thereby rests on the rollers. Also, the means for selectively imparting rotation to the cradle-supported processing drum can comprise switch means which is actuated by movement of the cradle to its horizontal position to commence rotation of the drive rollers and which is opened during movement of the cradle from its horizontal position. In the last-mentioned embodiment the rollers can be mounted either on, or separate from, the cradle.

Each of the above-described embodiments is considered to be within the broader aspects of the present invention which relate to the unique structural concept of providing selective stationary and rotative support means for a tubular processor with rotation to the supported drum being responsive to a change in its orientation.

DESCRIPTION OF PREFERRED EMBODIMENTS stationary housing 3 and the tiltable, tube drive and support cradle 4.

The processing tube 1 is comprised of a large cylindrical drum',5 and top and bottom end closures 6 and 7 respectively. Within the processing tube 1 is a liquid reservoir 8, which maintains liquid introduced through light-tight opening 9 out of contact with photographic material P in the processor.

When the processing tube 1 is positioned in a generally vertical orientation such as is shown in FIG. 2, the material P is I inserted in the processor in a single, nonoverlapping coil and expands by its own resilience against the interior walls of the processor housing. The material P is held against sliding and/or skewing by one edge under an L-shaped strip 10, see 1 FIG. 2. Also a spidered end plate 12 serves to prevent move ment of the material P while allowing drainage of used processing liquid through a drain opening 13 in the bottom end closure 7 when the processing tube I is oriented in the generally vertical position shown in FIG. 2.

The stationaryhousing 3 comprises back and sidewalls 31 p and a partial front wall 32, Upright support members 33 are correspondingly located on each sidewall31 and bearing ,notches 34 are formed at the same height on each upright support member 33. An adjustable stop member 35 is supported on an extension of the top of the back wall 31 to locate the cradle 4 in: its generally vertical position. A top 36 of partial front wall 32 serves as a stop for the cradle 4 in the horizontal position. The bottom of the housing 3 encloses a sump 37 for used liquids draining from the processing tube 1, see FIG. 2. The sump 37 can be removable or affixed to the housing 3 and a pump connected to discharge liquid therefrom.

The tiltable, tube drive and support cradle 4 comprises a boxlike frame 40 which is open at both ends. Referring to FIGS. 1 and 4 it can be seen that the frame 40 is formed of front and rear upright members 41, top and bottom longitudinal members 42 and crossmembers 43 which define a chamber in which the processing tube 1 can rest in a loosely supported relation. The framev40 also has middle longitudinal members 44 on opposite sides of which support lugs 45 extend outwardly at a location such that the frame can be easily pivoted in bearing notches 34 of the housing 3. A handle 46 is provided on the front of the frame 40 to facilitate pivoting the frame between the substantially horizontal position shown in FIG. I and the generally vertical position shown in FIG. 2. It is to bcnoted that the term generally vertical as used herein is intended to include positions of the cradle 4 and supported processing tube-1 which are upright, but not necessarily normal, with respect to the horizontalorientation. As best seen in FIG. 2, in the generally vertical osition the cradle 4 is pivoted slightly beyond a normal upright position through an arc of slightly more than 90 from its horizontal position in FIG. 1.

Between the front and rear bottom-crossmembers 43, a pair of longitudinal rollers 47 are mounted for rotation on shafts 48. By referring to FIG. 4, it can be seen that the rollers 47 are mounted in a generally uniformly spaced relation so that the processing tube 1 can rest with a portion of its peripheral surface between the rollers 47. It will be noted that the right roller 47, as viewed in FIG. 4, has its axis slight y nparallel with respect to left roller 47 to direct the drums toward the roller 54 thereby preventing the drum from creeping out of the cradle 4 during rotation. As can be seen in FIGS. 2, 4 and 5, a motor 49 is mounted n the rear of a lower cross member 43 and has a drive shaft 50 extending between the rollers 47, beneath the processing tube 1 in thelrprizomal cradle position. The drive shaft 50 is connected to one of the rollers 47 by pulleys 51 and 52 and belt 53.

in FIGS. 1, and 2, it can be seen that he cradle 4 also has a roller 54 mounted. thereon in a p ition to ngage and support an inclined section of a bottom end. closure 7 of the processing tube 1. The roller 54 supports the processing tube 1 as shown in FIG. 2 when the cradle 4 is in a generally vertical position and serves'as a bearing against which the processing tube 1 is urged during rotation of the processing tube 1 in the horlzorn tal position as sh wn in FIG. 1. The cradle, 4 also has a setbolt .55 which engages top 36 of partial f ont wall 32 in the horizontal position and an b u d to adjust the horizontal from position o a lev l condition. I

' In operation of the above-described embodiment, a sheet of material P can be inserted into the processing tube 1 while it is removed from the cradle 4. The top end closure 6 is removable from housing 5 for this purpose. The cradle 4 is moved to its generally vertical position shown in FIG. 2, and the processing tube 1 is placed in the chamber defined by frame 40 as shown in FIG. 2. The motor 49 is now started and can remain running through successive treatments of the material P. Drive is transmitted from motor shaft 50 to the connected roller 47. It slightly pass-normal be noted that nodrive is as yet transmitted to the processing tube because in the slightly-pastnormal position of the cradle 4 shown in FIGS. 2 and 3 the processing tube 1 rests against wall 43 of frame 40 and away from the rollers 47.

A change of processing liquid is introduced through opening 9 and passes into reservoir 8 within the housing 5 of the processing tube 1. The cradle 4 is then moved to the horizontal position shown in FIG. 1 and as the processing tube 1 moves to the horizontal position the liquid passes from reservoir 8 into contact with the material P. As the cradle 4 is moved from the vertical to the horizontal position, the processing tube 1 is moved by gravity within frame 40 to rest on rollers 47; and drive from the rollers 47 is transmitted to g the processing tube in the directions indicated by the arrows in FIG. 4.

When the desired processing time has elapsed, the cradle 4 is moved back to the original position shown in FIG. 2 and the processing tube 1 shifts by gravity back against the wall 43 of cradle 4 and away from the rollers 47. Transmission of drive from the rollers 47 to the processing tube lceases and the processing tube 1 is supported in the cradle 4' in a stationary disposition.

The next processing solution can then be introduced to reservoir 8 while used liquid drains from the processing tube 1 through opening 13 into the sump 37 as shown in FIG. 2. When the new charge of liquid hasbeen introduced and the used charge drained, the cradle 4 is again moved to the horizontal position shown in FIG. 1; and the next processing operation occurs in the same manner described above.

In FIG. 5 another embodiment of the present invention is disclosed. In this embodiment a crossmember 60 is inserted between the middle longitudinal members 44 of frame 40 at a position which will support a smaller tube 11 when the cradle 4 is moved to a vertical position such as disclosed in FIG. 2. The operation of this embodiment is otherwise the same as that described above. By referring to FIG. I, the one of a pair of retaining brackets 61 which are adapted to mount crossmcmber 60 can be seen.

It has been found that better processing results are achieved with both of the disclosed embodiments when a print to be processed in the drum 5 is treatedwith tempered water prior to application of any developer. This step serves both to preheat the drum 5 and to wet the emulsion surface of the paper. Prewetting the paper decreases the undesirable effects due to splatter and irregular wetting when liquid is discharged from reservoir 8.

The invention has been described in detail with reference to preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention as described hereinabove and as defined in the appended claims.
